Rhipsalidopsis plant named ‘PKMRhips06’

ABSTRACT

A new and distinct  Rhipsalidopsis  plant named ‘PKMRHIPS06’ particularly characterized by its compact plant habit; dense and bushy plant form; moderate growth rate and upright growth habit; rose/pink colored buds; and large, upright rose/pink colored flower.

Latin name of the genus and species of the plant claimed:Rhipsalidopsis×hybrida.

Variety denomination: ‘PKMRhips06’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofRhipsalidopsis, botanically known as Rhipsalidopsis×hybrida sometimesreferred to as Rhipsalidopsis Britton et Rose, including EpiphylopsisBerger, commonly known as either Easter Cactus or Spring Cactus, andhereinafter referred to by the cultivar name ‘PKMRhips06’.

The new Rhipsalidopsis cultivar is a product of a controlled breedingprogram conducted by the inventor, Christian Hald Madsen, in Søhus,Denmark.

The new Rhipsalidopsis cultivar originated from a cross made by theinventor in 2007 in Søhus, Denmark. The female and male parents areunpatented, proprietary Rhipsalidopsis×hybrida cultivars. The newRhipsalidopsis cultivar was discovered and selected by the inventor as asingle flowering plant within the progeny of the stated cross in acontrolled environment in 2010 in Søhus, Denmark. The inventor selected‘PKMRhips06’ on the basis of its flower color and compact, freelybranching, upright growth habit.

Asexual reproduction of the new Rhipsalidopsis cultivar by phyllocladecuttings was first performed in 2010 in Søhus, Denmark, and hasdemonstrated that the combination of characteristics as herein disclosedfor the new cultivar are firmly fixed and retained through successivegenerations of asexual reproduction. The new cultivar reproduces true totype.

BRIEF DESCRIPTION OF THE INVENTION

The following traits have been repeatedly observed and are determined tobe unique characteristics of ‘PKMRhips06’ which distinguish thisRhipsalidopsis as a new and distinct cultivar:

-   -   1. Upright growth habit;    -   2. Moderately vigorous growth; and    -   3. Rose Pink colored buds and flowers.

Data on the parent cultivars is no longer available for comparison withthe claimed cultivar.

The most similar commercial cultivar to the instant cultivar‘PKMRhips06’ is the Rhipsalidopsis cultivar ‘Gemini’ (Registered; CPVOGrant No. 20677). Plants of the instant cultivar ‘PKMRhips06’ differprimarily from plants of Rhipsalidopsis ‘Gemini’ in the followingcharacteristic:

-   -   1. Plants of ‘PKMRhips06’ have a more upright growth habit than        plants of ‘Gemini’, especially seen when grown as large plants;        and    -   2. Plants of ‘PKMRhips06’ have a brighter flower color than        plants of ‘Gemini’.

DETAILED BOTANICAL DESCRIPTION

The new Rhipsalidopsis cultivar ‘PKMRhips06’ has not been observed underall possible environmental conditions. The phenotype of the new cultivarmay vary with variations in environment such as temperature, lightintensity, and day length without any change in the genotype of theplant.

The aforementioned photographs, together with the followingobservations, measurements and values describe plants of ‘PKMRhips06’ asgrown in a glass-covered greenhouse in Fyn, Denmark, under conditionswhich closely approximate those generally used in commercial practice,where day temperatures in the greenhouse average 18° C. and nighttemperatures in the greenhouse average 16° C. Ambient light levels usedwhile growing plants of ‘PKMRhips06’ are +50 Wm². No growth retardantswere used when growing plants of ‘PKMRhips06’.

The age of the ‘PKMRhips06’ plants described is about 10-12 months oldand grown in 5 cm pots. The photographs and descriptions were takenduring the winter season. Color references are made to The RoyalHorticultural Society Colour Chart (R.H.S.), 5^(th) edition, exceptwhere general colors of ordinary significance are used.
